Preisner SPU88T Low Noise Block downconverter

The Preisner SPU88T Low Noise Block downconverter by Televes receives satellite signals in the 10.7 - 11.7 GHz band and downconverts them for use with standard satellite receivers. Designed with a 4 cm feedhorn and an anthracite finish, the SPU88T provides signal conversion with low intrinsic noise while drawing 200 mA of power. The compact design is suitable for installation on a variety of parabolic dishes and satellite reception setups.

Advantages

The SPU88T delivers reliable frequency conversion across the specified Ku-band range with consistently low noise figure for improved signal-to-noise performance. The small feedhorn diameter simplifies mounting on small and medium dishes while the modest power consumption allows easy integration into typical satellite LNB power supplies. The anthracite housing provides discreet appearance and weather-resistant styling appropriate for outdoor use.

Suitable for

• Domestic and small commercial satellite TV reception in the 10.7–11.7 GHz range
• Replacement or upgrade of existing LNBs on compatible parabolic dishes
• Setups where compact feedhorn size and low power consumption are preferred

Key specifications

• Operational frequency range: 10.7–11.7 GHz
• Feedhorn diameter: 4 cm
• Power consumption: 200 mA
• Color / finish: anthracite
• Device type: low-noise block downconverter (LNB)

How to use

Mount the LNB at the focal point of a compatible parabolic dish following the dish manufacturer’s alignment instructions. Connect the coaxial cable from the LNB output to the satellite receiver input and ensure the receiver provides the required supply voltage over the coaxial cable. Adjust dish azimuth and elevation for the target satellite and fine-tune for maximum signal strength and quality as indicated by the receiver.

Recommendations

For best results, use a properly sized dish for the intended satellite orbital position and maintain secure weatherproof cable connections. Periodic inspection of the feedhorn and housing for physical damage or water ingress will help sustain low-noise performance. When replacing another LNB, verify the receiver settings and cable polarity to ensure correct operation.
